Me too, I've done pretty much all of alpha on veteran solo, all but the two mandatory Co-op mission on Bravo veteran (i'm missing overwatch and big brother), I've done all of Charlie apart from Snatch and Grab veteran, and I've done Armor Piercing on Veteran Solo for Echo.

So what I'm missing is Overwatch, Big Brother, Snatch and Grab, Wardriving, Wreckage, Acceptable Losses (can prob do this solo), Terminal, Estate Takedown and High Explosive.
